Yann LeCun to depart Meta and launch AI startup focused on 'world models'

Making LeCun report to Wang was the most boneheaded move imaginable. But… I suppose Zuckerberg knows what he wants, which is AI slopware and not truly groundbreaking foundation models.

In industry research, someone in a chief position like LeCun should know how to balance long-term research with short-term projects. However, for whatever reason, he consistently shows hostility toward LLMs and engineering projects, even though Llama and PyTorch are two of the most influential projects from Meta AI. His attitude doesn’t really match what is expected from a Chief position at a product company like Facebook. When Llama 4 got criticized, he distanced himself from the project, stating that he only leads FAIR and that the project falls under a different organization. That kind of attitude doesn’t seem suitable for the face of AI at the company. It's not a surprise that Zuck tried to demote him.

LLM hostility was warrented. The overhype/downright charlartan nature of ai hype and marketing threatens another AI winter. It happened to cybernetics, it'll happen to us too. The finance folks will be fine, they'll move to the next big thing to overhype, it is the researchers who suffer the fall-out. I am considered anti LLM (transformers anyway) for this reason, i like the the architecture, it is cool amd rather capable at its problem set, which is a unique set, but, it isnt going to deliver any of what has been promised, any more than a plain DNN or a CNN will.

Meta is in last place among the big tech companies making an AI push because of lecun’s llm hostility. Refusing to properly invest in the biggest product breakthrough this century was not even a little bit warranted. He had more than enough resources available to do the research he wanted and create a fantastic open source llm.
